are observed in the structure [Fe(C5Me5)2](BA) (1) of 1:1 composition. Interestingly, the structures [Fe(C5Me5)2](CA)(H2O) (2) and [Fe(C5Me5)2](CNA)(H2O) (3) of 1:1:1(H2O) ratio contain one-dimensional molecular tape structures with the combination of the CA or the CNA units and water molecules via O–H⋯O hydrogen bonds. Different stoichiometric ratios and structures are found from the CNA complexes
使用双(五甲基环戊二烯基)铁Fe(C 5 Me 5)2作为有机金属供体和三个苯甲酸(2,5-二溴-3,6-二羟基-1,4-苯醌),BA,2,5合成了四种配合物-二氯-3,6-二羟基-1,4-苯醌; CA和2,5-二氰基-3,6-二羟基-1,4-苯醌; CNA)作为有机受体。这些配合物具有不同化学计量比[1:1,1:1:1(H 2 O)和2:1]的分子结构已经通过X射线晶体学分析和元素分析确定。这些络合物具有一维交替堆积的排列方式,即⋯D + A − D + A −⋯类型。在1:1组成的结构[Fe(C 5 Me 5)2 ](BA)(1)中观察到BA单元的溴原子和氧原子之间的紧密接触。有趣的是,结构[Fe(C 5 Me 5)2 ](CA)(H 2 O)(2)和[Fe(C 5 Me 5)2 ](CNA)(H 2 O)(3)为1: 1:1(高2O)比包含一维分子带状结构,其中CA或CNA单元与水分子通过O–H
